Application filed December 22, 1905. Serial No. 292,933.

the county of Essexand Commonwealth of Massachusetts, have. invented certain Improvements in Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings-indicatin like parts in the severalfigures.

iis invention relates to heels for boots'or shoes.

In the manufacture of boots-and shoes, as

by machines which act first to press the heel upon the heel seat of the shoe with considerable pressure and then to drive the attaching nails into the heel. It is desirable that the heel be positioned accurately upon its seat in the operation of driving the nails, for while a sli ht inaccuracy in position may be at times en stantiall'y cured in trimmin the heel, this cannot always be done, and if t 1e inaccuracy be considerable it ma be impossible to trim the heel to secure t e s mmetry of form desired.

An object ofrmy invention is to provide a heel which will facilitate an accurate location of the heel upon theboot or shoe preliminary to driving the nails. The heel seat of a boot or shoe, as is well known, is the grain side f the leatherand immediately prior to the heel attaching operation is commonly ui-te smooth. There is some liability of a eel slipping upon this smooth surface when pressed upon it and consequently being displaced. Such liability is considerably increased when the heel seat face of the heelis the grain side of the leather and has been subjectedto the action of. the heel compressor,

which, as is well known, in molding heels ime parts a'hig'h degree of smoothness to their exterior surfaces on account -of the extreme pressure which" the dies ofthe machine impart tothe heel. V I

It has heretofore been generally regarded as impracticable, mainly or reasons such as that above given, to make the heel seat face of the heel the grain side of the leather although there are, considerations which render1t desirable. For example, where compressed heels are sold as a separate article of manufacture it is of course esired to make their appearanceas attractive as possible and -of the heel marrin t e sole when the heel is the appearance of the heels is much improved if their exterior faces and particularly their heel seat faces are somewhat finished. The natural smoothness of the grain side of the leather is such that where this side is outside the dies of the heel compressor make it extremely smooth, giving the leather a more attractive appearance than where'the flesh side is outsi e. invention consists in molding upon the eel seat face of a heel a series 0f;pro'

' jections comprising parallel ridges which will impart to said face a degree of-rou 'hness that wil prevent displacement of the heel in the heel attaching operation. The heel seat lift of the heel is preferably arranged with its grain side outside so that thisface of the heel after being acted upon by the heel com pressor wil be in a highly finished condition.

, Other features of the invention will be hereinafter described and defined in the claims.

In the drawings, which illustrates. heel forming one embodiment of the invention, Figure 1 is a perspective. view of the heel; Fig. 2 is a perspective view of a portion of the heel-enlarged; and Fig. 3 is a vertical longitudinal section of the heel. p The heel shown is formedof a series of superposed lifts, the heel seat lift or inner lift being. arrangedwith the grain outside and the remaining lifts having their flesh sides uppermost, as indicated in the several figures. The heel is molded in a compressing machine to impart to it the desired form and density. In the molding or com ressing 0 eration the'heel seat face of the eel is suita 1y indented or embossed to roughen, it so that when pressed upon the heel seat it will not slip from the position desired. The bevel2 at the breast of the heel is preferably left smooth for the reason that it is unnecessary to roughen this face and the general. appearance of the'heel is improved if it is left smooth and also because liabilit is thus pre vented of the sole being marre by pressure of such aroughened face upon it in a't'taching the heel, The purpose of the bevel 2, as is well known, is to revent the breast edgeresse'd upon the eel seat part of the sole. he rojections formed are preferably evenly distributed over that plart of the heel on which they lie. In the eel shown, the pro- I seo,eee

entire area of said face/so that the extent of roughened surface in contact with the heel seat of the shoe. will be as great as possible. The series of ridges 3 and 4 upon the heel constitute penetrating projections which, When the heel is pressed upon the heel seat in the operation. of the heel attaching machine, will indent or enetrate to a limited v extentthe heel seat race and thus prevent displacement of the heel. The PIOJGGtlOIIS upon the heel seat face of the heel are pref erably arranged as shown in Fig. 1 to ex tend not quite to the extreme edge of said face. This-feature is of advantage in that it permits. a portion of the stock to he ren oyed in the heel trimming operation with out causing the projections to he visible at the sides orcurved end of heel.

Having described my invention, What I claim as new and desire to secure lay-Letters Patent of the United States isz- 1. A heel having upon its inner surface penetrating projections formed and arranged to indent-the heel seat of'a shoe and comprising parallel ridges extending from side to side of the heel.

3 a I 2. A. heel, having upon its lnner surface penetrating projections formed and ar ranged to indent the heel seat of a shoe and comprising a plurality ofsets of parallel Y ridges, the ridges of one set'being arranged at an angle to, and intersecting the ridges of I another set.
